Epidermodysplasia verruciformis (EV) is a rare genodermatosis characterized by abnormal susceptibility to infection with b-genotype human papillomavirus (HPV) and a particular propensity to develop cutaneous malignancies. Clinical manifestations include flat, scaly, reddish hypo- and hyperpigmented macules, verruca-like papillomatous lesions, seborrheic keratosis- like lesions, and pink-red pityriasis versicolor-like lesions1.

The biomarker for left ventricular hypertrophy (LVH) in patients with essential hypertension (EH) remains an unmet clinical need. The microRNA-30 (miR-30) family has been associated with LVH in cellular and animal studies, but not in a clinical setting. ⋯ Circulating miR-30e level can be used as a biomarker in distinguishing EH-LVH from EH-nLVH. A further prospective study is warranted to validate this finding.

While the outcome of patients with multiple myeloma has significantly improved over the last two decades, the disease remains incurable for the majority of patients. With the advent of novel agents, there has been a shift towards prolonged therapy as opposed to fixed-duration therapy, aimed at improving progression-free survival and overall survival. Evidence favoring continuous therapy has emerged over the last 2 decades and in the context of maintenance after proteasome inhibitor plus immunomodulatory drug induction followed by high dose melphalan and stem cell transplantation, this leads to >80% overall survival at 5 years. ⋯ As the survival improves, it is crucial to identify patients who are projected to have better survival and spare them toxicities arising from indefinite maintenance therapy. The role of minimal residual disease in this context is being investigated in numerous clinical trials and in the next few years the goal should be to use this in a rational way to achieve the ability to identify patients who would require continuation or escalation of therapy to improve their projected survival as well as to identify the group of patients in whom maintenance therapy could perhaps be time-limited without compromising their survival. Here we review the evidence for maintenance therapy from the key trials in the past years, present an overview of the current landscape and our perspective of maintenance therapy in the future.

Observed Frequency and Characteristics of Hearing Loss in Osteogenesis Imperfecta.
Osteogenesis imperfecta (OI) is a rare group of genetic disorders affecting connective tissue, with consequent bone fragility, frequent fractures and skeletal deformity. Depending on the type, patients can have blue sclera, dentinogenesis imperfecta, and hearing loss. ⋯ In this group of patients with OI, 30% had hearing loss and among those ears with normal hearing, 13% did not have an acoustic stapedial reflex. Patients with OI should be monitored for hearing loss.
